The World Bank's initial approach to road project and network evaluation was to develop a program to do project evaluation. Over the years this has gradually been modified to also do testing of maintenance strategies on a single pavement and then more recently to adapt it to also do strategic analysis of a road network to determine budget needs over a long period or to test the effect of a particular budget level over a long period. The National Association of Australian State Road Authorities (NAASRA) started with a set of programs to assess required budget levels over a given period. Later, individual States developed their own project evaluation programs independent of the NAASRA strategic program set. This paper describes the strengths and weaknesses of the two approaches for doing strategic analyses. It illustrates the advantages of using a purpose designed system for strategic evaluation, rather than trying to make one program do all things.
